High voltage beer

Whilst browsing the net doing some research, I came across this video.

Watch the fluid currents created by the electrical currents.

Cool.

(And, please, no comments about wasting beer - it looks like it's only a lager.)

That is really impressive! The transitions between metastable discharges and chaotic breakdowns are really surprising. The convection currents make sense, since you're getting very localized heating. Good job on the research front!

Do you not think that the currents could be (literally) electrical? The high voltage could be splitting something in the beer into charge carriers, and they could be moving through the beer?
Hmmmm...theoretically, I suppose. I don't know quite enough about o-chem, but I don't think beer has a lot of electrolytes (ionic species); certainly no salts, and alcohol doesn't behave that way.

At this point I'd defer to the opinion of a professional chemist; hey, Lemonie!
Beer will have salts in it from the water, and naturally carbonates. I see de-gassing and mist formation, which are going to promote plasma formation.

Actually, I was thinking wrong - not generating ions, but shoving electrons around (like the way a static charge will bend the flow of a stream of water).

I have no idea what you just said but it sounds awesome!
Here, allow me (Google Translate does not list the language yet but I speak a little Kelsese):

That is really impressive! The transitions ({translator's note} Or, fact that the periods of activity change at all?) between periods of delicate balance and periods of stuff going all disorganized and breaking down are really surprising. The curents from heat exchange between areas with different temperatures within the beer makes sense, since you're heating a very small area. Good job on the research front!

Consider it a "colloquial" translation - dunno how terribly accurate it is. I'm still learning (there's hardly anybody to speak it with!) :P
Har, har! Thank you very much. Are you offering to become my flapper (Swiftian, of course)?
Haha! Yeah, sure, if you're cool with me touching your face with a dried bladder...

AAAAAAAAAAAAAAAAAAAAAGH HIGH-PITCHED NOISES!!! The HV supply is emitting a constant tone at something like 18kHz (measured with my "sounds like 18kHz-ish" system), and GOODNESS it's annoying. Bleeding eardrums aside, very cool video!
